public final class DefaultObjectService extends AbstractService implements ObjectService
ObjectCreatedEvents, and removes objects
from ObjectDeletedEvents.
This is useful to retrieve available objects of a particular type. For
example, the InputHarvester infrastructure uses it
to provide a pool of available objects for widgets such as the
ObjectWidget, which provide the user with a
multiple-choice selection.

the service framework itself (specifically by the ServiceHelper)
when initializing the service. It should not be called a second time.
